Description

For some Packet Captures it's useful to log the results to an external FTP Server. SonicWalls can only capture as much traffic as the models internal buffer memory allows, when this is full the Packet Monitor will stop capturing traffic, or begin to delete the oldest captured traffic. Logging to an FTP Server allows an Administrator to perform longer term captures which can be useful for troubleshooting intermittent issues or providing captures to SonicWall Technical Support for examination.

TIP: If you're sending Packet Captures via FTP to a particular Software solution, such as Filezilla, please reference their documentation to ensure the Server is ready to receive data.

If you're unfamiliar with the SonicWall Packet Monitor Feature please reference How to Setup and Utilize the Packet Monitor Feature for Troubleshooting.

Resolution

Resolution for SonicOS 7.X

This release includes significant user interface changes and many new features that are different from the SonicOS 6.5 and earlier firmware. The below resolution is for customers using SonicOS 7.X firmware.

1. Login to the SonicWall Management GUI
2. Navigate to the MONITOR Tab in the top navigation menu.
3. Under Tools & Monitors settings, click Packet Monitor.
4. Under Packet Monitor, navigate to the General Tab and click on Logging.

5. In the FTP Server IP Address field type the IP address of the FTP server. Ensure that the FTP server IP address is reachable by SonicWall.

CAUTION: IP Addresses that are reachable only via a VPN Tunnel are not supported.

6. In the Login ID field, type the login name that SonicWall should use to connect to the FTP server.

7. In the Password field, type the login name that SonicWall should use to connect to the FTP server.

8. In the Directory Path field, type the directory location for the transferred files. The files are written to this location relative to the default FTP Root Directory. For example: If the Root Directory of the FTP server is "FTP" and a sub-folder named "Capture Files" is created, enter "Capture Files" in the Directory Path.

9. To enable automatic transfer of the capture file to the FTP server when the buffer is full, select the Log To FTP Server Automatically checkbox.
